What data type is suitable for data that has a fixed format and can be easily organized into tables?

Structured data refers to data that is organized in a predefined manner, typically in tables with rows and columns. This type of data is easily searchable and can be efficiently processed by algorithms and databases due to its clear format. Examples of structured data include data stored in relational databases, where each field has a defined type (such as integers, dates, or strings) and the relationships between different pieces of data are well-defined.

In contrast, unstructured data lacks such a format and does not fit neatly into tables, making it more challenging to analyze. Categorical data consists of labels or categories that can be used to organize data but may not have a fixed structure. Numeric data refers specifically to data that is quantitative, which can be structured but does not encompass the broader definition necessary for the question. Thus, structured data is the most appropriate answer because of its fixed format and compatibility with tabular organization.
